LAMBREQUIN non oo'rron GINS.

Application filed October 11, 1928. Serial No. 3. .1,?82.

This invention relates to new and useful improvements in lambrequins for cotton gins. p

lnthe ginning of'cotton it is customary to 5 employ a toothed or comb-like bar at the bottoni of the roll box just over the huller ribs .to support the roll of cotton. Those lambre quins now in common use are usually made by driving steel pins into a previously bored 10 pipe or red, so that the pins extend at right angles to the longitudinal axis of the pipe or bar. Such pins break, bend and becomeloo'se, thus interfering with the operation of the gin. I One object of the invention is to provide a lambrequin with integral teeth or fingers formed in a new and novel manner and making for increased strength and more economical manufacture.

Another object of the invention is to provide a lambrequin with downwardly curved teeth, either in the form of integral teeth or the usual driven pins, overlying the huller ribs, whereby. the seeds are more quickly re- 25 leased and the cotton is more rapidly-handled,

thus increasing the ginning capacity.-

A construction designed to carry-out the invention will be hereinafter described, to gether with other features of the invention.

fi'cation and by referenceto theflaccom'pany ing drawings, inwhi'ch an example of the invention is shown, and wherein z quin equipped with curved fingers.

In reference to the drawings the numeral 10 designates a rib rail commonly used in gin stands for the purpose of supportingribs 11, sometimes referred to as huller ribs, which when correctly spaced between apluralityof gin saws 12 mounted on a saw shaft'13 and heldequidistant by spaced blocks l lwill remove fromthe cotton, that is pulled between The invention will be more readily understood from a reading of thefollowing speci F 1 is a partial transverse sectional those ribs by the saws, all hulls and trash which flows into the gin. p After the cleaned cottonhas passedthe ribs 11, it is brought into contact with another set of ribs l5 which are spaced closeenough to the saws to remove the seed from the cot ton. These ribs are so shaped as to cause the cotton that is not pulled immediately there through, to roll on top of-the saws. It iscustomary to use a lambroquin and one of the ordinarytype is shown in F 5, except that it is equipped with curved fingers 17 and such fingers are not now in common use and constitute part of the invention. The

head 16 having a plurality of curved fingers 17 driven therein which are particularly shaped to closely conform to the curvedtops of the ribs 11, whereby these ribs not only support said curved fingers, but prevent them from bending or breaking. The curved fingers arevei-y advantageous andare a new departure in the art.

Another and more improved form of lambrequin isshown in Fig. 4:. The fingers l8 are made integral with the cylinder shaped head 19. These fingers are die-pressed or suitably formed so as'to be curved longitudinally and U-shapedin, cross-section as is illustrated in F 3 so as to give them sufiicient strength. Shanks 2Q connect, the fingers with the head 19 and are reinforced byribs: 21 which; are pressed in these, shanks and merge into' the head. The shanks provide a substantial and rigid connection between the head and fingers and reduces thetend'ency of the fingers to break off. 7 v v The lambrequin is made from a suitable sheet of metal and the process of manufacture is as follows: a blank sheet of metal is cut the proper length and width. It is then placed in a press and the fingers and shanks with their reinforcing ribs are cut therefrom and formed. The partially formed lambrequin is then taken to a roller and the cylindrical head rolled. By this method a very crude means of manufacturing is eliminated.

. The lambrequin now'commonly manufactured, is made of pipe or tubing. Holes requires a considerable amount of time and ion labor. Thus it is evident that by forming the as V fingers and head in two operations of a single sheet of metal a considerable amount of time and labor can be saved.

After the stamped lambrequin is formed a core bar 22 is inserted in the head 19. This bar is held therein by any suitable means, such as rivets 23. The purpose of this bar is to strengthen the head and prevent it from bending as is the case with the old style lambrequin when the fingers or pins are driven therein.

In applying this new type lambrequin to "the roll box of a cotton gin it is quite evident eliminated. Further, lint cannot lodge between the fingers and the huller ribs.

Various changes in the ,siZe and shape of the difi'erent parts, as well as modifications and alterations, may be made within the scope of the appended claims.

' What I claim, is:

1. A lambrequin for cotton machinery including'a plurality of curved fingers.

2. A lambrequin for cotton machinery including a plurality of downwardly curved fingers.

3. The combination with the huller ribs and roll box of a cotton gin, of a lambrequin mounted at the bottom of the roll box and including a plurality downwardly curved fingers overlying said huller ribs.

4. The combination with the huller ribs and roll box of a cotton gin, of a lambre'quin mounted at the bottom of the roll box and including a plurality downwardlycurved fingers.overlyingjsaid hullerribs, said fingers being curved contiguously to the huller ribs.

A lambrequin for cotton machinery including a longitudinal head and fingers formed from the same sheet of metal as the head and extending from the head, said fingers being curved downwardly.

6. A lambrequin for'cotton machinery comprising an elongated cylindrical head and extended fingers, all out and formed from a single sheet of metal, said fingers being U-' shaped in cross-section and curved downwardly.

7. A lambrequin for cotton machinery including a longitudinal cylindrical head, a core bar inserted in the head, and fingers merged from the head and curved downwardly therefrom and formed integral therewith.

8. A lambrequin forcotton machinery in cluding a cylindrical elongated head, finger shanks bent from one side of the head, fingers extending from the shanks and into which the shanks are merged, said fingers being U- shaped in cross-section, and reinforcing ribs pressed in the shanks and extending from the fingers to the head. 7 A

9. A lambrequin for cotton machinery comprising an elongated cylindrical head and fingers extending from one side of the head and cut from the same sheet of metal, the

fingers having flaring shanks merging into the head. i

10. A lambrequin for cotton machinery comprising an elongated cylindrical head and fingers extending "from one side of the head and cut from the same sheet of metal, the fingers being U-shaped in cross-section.

11. A lambrequin for cotton machinery comprising an elongated hollow cylindrical head and fingers extending directly from the head and substantially tangentially therefrom, the head and fingers being formed in one piece.

12. A lambrequin "for cotton machinery comprising an elongated cylindrical head and fingers extending from one sideof said head, the fingers and head being formed. of one piece of metal, and a core extending through the head and secured therein for reinforcing the lambrequin.
